What are some best practices for handling and manipulating text in PHP to achieve the desired output?

When handling and manipulating text in PHP to achieve the desired output, it is important to use built-in functions such as `strlen()`, `substr()`, `str_replace()`, and `explode()` effectively. These functions can help with tasks like counting the length of a string, extracting a substring, replacing specific characters, or splitting a string into an array based on a delimiter. Additionally, regular expressions can be powerful tools for more complex text manipulation tasks.

// Example: Using str_replace() to replace a specific word in a string
$text = "Hello, World!";
$newText = str_replace("Hello", "Hi", $text);
echo $newText;
